4 Introduction Innovating and beautiful design, seven different sizes, high control flexibility and easy maintenance: the Trane chilled water cassette is the result of an extended technical and design development aimed at achieving the highest level in terms of performance, silent operation and control possibilities. The air diffuser has a highly attractive aesthetical appearance, very innovative, and is also able to offer the best air distribution performance thanks to long computer studies and laboratory tests. The standard color is RAL 9003; other colors are available on request. The smaller sizes are designed to fit into 600x600 mm false ceiling standard modules. The bigger sizes have a dimension of 800x800 mm which allows the best outcome in terms of sound levels and of price/ performance ratio for these high capacity models. Units can be supplied with Electronically Commutated fan motors, which mean: 76% energy savings New electronic controllers with wall thermostat or infrared remote control. Variable speed ventilation which avoids shifts in sound levels by modulating the fan speed to the exact operating needs. Every unit can be supplied with 1 coil (2-pipe system) and a possible electric heater or with 2 coils (4-pipe system). Each model can have fresh air intake and a remote air diffuser can be connected to the unit. The condensate pump integrated into the unit as standard, is very quiet and has a maximum head of 650 mm. In addition to the temperature and speed standard controls, automatic speed selection is also available. More than one unit can be connected to a single control, and the unit control panel is installed in a position that facilitates the maintenance operation. Every unit can also be operated by the means of an infra-red remote control. The cassettes can also be connected to the most common automatic building management systems thanks to the Trane ZN LonTalk control. A factory-mounted and tested 2-way or 3-way valve kit can be proposed to save time on the job site.

18 Air throw The air throw indicated in the tables must only be considered as the maximum value, as it may change significantly depending on the dimensions of the room in which the unit is installed and the positioning of the furniture in the room. The useful throw L refers to the distance between the unit and the point where the air speed is 0.2 m/ sec; if the louver has a gradient of 30 (recommended in cooling mode), the so-called "Coanda" effect will occur, illustrated in Figure 6, while at a gradient of 45 (recommended in heating mode), there will be a downwards throw, as illustrated in Figure 7. Note In heating mode, you must pay attention to rooms where the floor temperature is particularly low (for example less than 5 C). In this situation the floor can cool the lower layer of air to a level that stop the uniform diffusion of the hot air coming from the unit, decreasing the throw figures shown in the table.

19 Fresh air inlet The unit is fitted with inlets for fresh air to be mixed with return air inside the unit. The fresh airflow is limited to 20% of the total fan coil airflow at medium speed and 100 m 3 /h for each treated air inlet. The units feature fresh air inlets on three corners (no inlet on the fourth corner because of the condensate pump inside the unit). The fresh air inlets are designed for the insertion of standard 110 x 55 mm rectangular ducts. The air duct is connected quickly and easily. After removing the blank and the insulation inside the unit, the mounting plate is rolled back and the air duct with its V-shaped section must be pushed into the unit. The duct is then fixed to the mounting plate. Note: Fresh air must be filtered. Figure 10 - Air flow 1 = Air distribution 2 = Main air inlet 3 = Air intake 19

21 Air distribution Two air outlets are provided on the side of the unit for connection to separate supply air outlets. They can be used to supply air from the fan coil unit to distant areas of a room or even to a different room. The total airflow does not change. The air flow at high speed depending on the air duct pressure drop is shown in the tables below. Note: All air ducts must be insulated in order to avoid condensation.

30 Group controls Figure 16 - CWS grille with infra-red receiver for units with AC fan motor Group control via ModBus communication protocol through RS485 serial link The MB controller is suitable for AC and EC fan motor technology. It can be connected to one T-MB thermostat or RT03 infrared remote controller field installed. One device can control up to 20 units in a Master/Slave configuration with ambient temperature controlled based on thermostat or on return air temperature sensor. When connected to the centralized time of day scheduler TODS controller, up to 60 units can operate together on the same agenda for 7 days each operating on individual set points and fan control. For rooms where set points and fan operation is left to occupants the MB controller can be connected to one T-MB thermostat or RT03 infrared remote control. In this case the latest command from any of the connected devices thermostat T-MB / RT03 or TODS is executed by the MB controller. If more than 60 units have to be installed in the building operating under the same TODS agenda, some terminal units serving the same zone in an open space shall be installed without control. It will be connected to a unit with MB controller using a relay card REL03 for units with AC fan motor or in a wired daisy chain arrangement for EC fan motor but with a limitation to 10 units in this case. The same strategy shall be used for zones where several units shall be installed so only one user interface T-MB or RT03 is required per zone for several units. System configuration More over, the TODS centralized controller is capable to pilot up to 8 external devices like a chiller or an air handler using the external control card ECC. Each external device can provide the state of operation to the TODS controller to provide a diagnosis about the installation. Such the MB control using ModBus communication protocol is a powerful device that can operate a small building in a system configuration. Configuration and commissioning The MB controllers are factory configured for the application. The terminal address and operating parameters are configured on the controller using dip switches which make the commissioning accessible to anyone reading simple instructions in the installation manual. 30
